Slide out floor loose from wall

[josepho918]

Hi, I'm selling my 2004 Keystone Everest 364Q with lippert hydraulic slides to my sister and her husband and I'm trying to fix everything before the sale. Here's the problem, I accidentally stepped on the slideout floor when the slideout was in and the floor came loose from the slideout’s side wall. Today I tried to locate the screws the secured the floor to the wall but had no luck. I know it’s secured by screws because when I stepped on it I herd the screws strip the holes. If anyone knows how to access the screws or has an idea how it can be fixed it would be greatly appreciated.
